CUTTING AND EMBYOSSING MACHINE.-

STEEGIFICATION forming part of Letters Patent No. 684,989, dated October22, 1901.

Application filed July 24, 1900.

of Iowa, have invented a new and useful Out ting and Embossing Machine,of which the following is a specification.

My present invention relates to a novel cut-' ting and embossing machinedesigned particularly for the use of photographers and adapted to beutilized for the cutting of oval or other forms of photographic paper ormounts and for the embossing of card-mounts.

The object of the invention is to produce a simple and inexpensivemachine of the character specified comprehending a plunger and powerfuloperating mechanism'for reciproeating the plunger to operate a cutter oran embossing-die, said die andcutter being arranged for interchangeableconnection with the plunger with facility.

A further object of the invention is to provlde the machine with inkingmechanism to permit embossing in colors, said mechanism being controlledby a trip device operated by.

the plunger to cause the inking of the die upon the retraction of thelatter and equipped with means for retaining the trip out of operativerelation with the inker to prevent the actuation of the latter when theplunger is utilized in connectionwith the cutter,

A still further object of theinvention isto economize the powernecessary for the operation of the machine by providing a novelantifrictional connection between the plunger and the plunger lever orrocker and by embodying an operating-toggle in the operating oractuating mechanism to insure the effective operation of the plungerupon the application of minimum power to the outer end of an extendedoperating-lever.

Further and subordinate objects will hereinafter appear as the necessityfor their accomplishment is developed in the succeeding description,taken in connection with the accompanying drawings, in which I haveillustrated a preferred embodiment of the invention.

In said drawings, Figure 1 is a side elevation of my machine completeorganized for embossing purposes, the plunger being shown retracted andthe inking-roller presented to Serial No. 24,737. (No model.)

the face of the embossing-die and the position of certain of the partsat the opposite limit of their movement being illustrated indotted'lines. Fig. 2 is a front elevation of the subject-matter of Fig.1 Fig. 3 is a sectional elevation of the machine organized for use inconnection with the cutter, one side of the frame being broken away todisclose interior parts. Fig. 4' is a detail perspectiveview of theplunger. Fig. 5 is a similar view of the die-holder,-and Fig. 6 is adetail perspective View of the cutter-head.

, Referring to the numerals of reference employed to designatecorresponding parts in the several views, 1 indicates the frame-bed ofmy machine, formed with a depression or seat .2 for the receptionof adie-block 3 and supporting adjacent to one end a hollow standard 4, fromthe u pperextreinityof which extends a horizontal hollow arm 5, formedat its-end opposite the. standard with a cylindrical sleeve orplunger-socket 6, disposed vertically above the die-block 3.

The frame of the machine, comprising the structural features recited,with the exception of the block 3, is preferably produced in the form ofa hollow casting made up of identical longitudinal sections boltedtogetherafterthe assembling of interior parts by bolts 7, for thereception of which each section of the frame is provided with bolt lugsor ears 8, coincident with similar ears on the other section. Disposedvertically above the dieblock 3 and mounted for reciprocatory movementin the plunger-socket 6 is a cylindrical plunger 9, formed with anapertured head 10 at its upper end and with a transverse recess orball-socket 11 at a point intermediate of its length. The ball-socket 11is located to move in a path coincident wit-h the vertical diameter ofthe frame-arm 5 as the plunger is reciprocated and is designed for thereception of the spherical orball end 12 of a plunger lever or rocker13, fulcrumed medially upon a shaft or pintle 14 located adjacent to theupper rear corner of the frame. The plunger-lever 13 is designed to beoscillated to effect the reciprocation of the plunger by anoperating-lever 15, of substantially bell-crank shape, inasmuch as itsrear end 16 is angular for pivotal connection, as by a knuckle 17 ,withan upstanding swingand having its rear end cured to the plunger ing link18, mounted to oscillate upon a shaft or pintle 19, which, like thepintle 14 of the plunger-lever, extends between the sidewalls of theframe and serves as additional securing means for uniting theframe-sections.

The pivotal connection between the operating-lever 15 and theplunger-lever 13 is effected at the angle of the former by a pintle 20,which, like the knuckle-pintle 17, is disconnected from the frame and isfree to move bodily as the parts are operated. This form of connectionserves to incorporate a toggle in the plunger operating mechanism, thebearing-points of the toggle being defined by the pintles l9 and 20 andthe knuckle 17, the lateral movement of the knuckle of the toggle beingeffected by the oscillation of the operating-lever 15, which is extendeda su-fiicient distance to obtain the desired leverage. For theaccommodation of the operating-lever, which necessarily extends abovethe frame, the latter is provided with a more or less extended slot 21,and the retraction of the plunger after its actuation by the depressionof thelevcr 15 is effected by a stout spiral spring 22, connected at itsupper end to the link lS, adjacent to the knuckle 17, and at its lowerend to a lug 23, integral with the frame and located a suitable distancein advance of the lower end of the link. It will now appear that as theoperating-lever is depressed the toggle defined will be extended againstthe resistance of the spring 22 to rock the plungenlever 13 and causethe depression of the plunger for the presentation of the tool to theface of the die-block, the ball and-socket connection between the lever13 and the plunger rendering the movement of the latter practicallyantifrictional.

The construction of the machine as described comprehends a completeembodiment rot my invention in its broadest aspect, inasmuch as theplunger-operating mechanism constructed as shown may be employed invarious connections other than that for which the present machine isparticularly designed; but as my particular object is to equip themachine for the cutting of photographic paper and the embossing ofcard-mounts I have originated simple and eificient devices by theemployment of which the machine may be quickly converted for cutting orembossing purposes, as the case may be.

In Fig. 1 of the drawings I have shown the lower end of the plungerfitted into the end of a die-holder 21, which is detachably seby aset-screw 25. The under face of the holder 2% is formed with aguide-channel 26 for the reception of the embossing-die 27, retained byabutment-screws 28, piercing one wall of the die-holder, as clearlyillustrated in Figs. 1 and 5.

When itis desired to substitute the cut tingtool for the embossing-tool,the latter may be readily removed from the ing the set-screw 25, and thecutter 29 trated inv Figs. 3 and 6 of the drawings plunger by loosen-(illus- (may be quickly substituted. The form of the cutter-head 29 willdepend upon the desired contour of the cutter; but in any event it isprovided, like the die-holder, with an annular flange pierced by aset-screw 30, detachably retaining the head of the plunger. Thecutter-head 29, constructed in accordance with my invention, is providedwith a depending flange 31, of oval or other form and of less diameterthan the head,to provide a seat for the cutter or blade 32, of similarform, and retained securely against the flange 31 by a cut tor-retainingring 33, preferably shrunk into place.

For the purpose of insuring the detachment of the paper or mounts fromthe cutter when the plunger is retracted the cutter-head is formed initsunder face with a spring-seat 34, preferably coaxial with the plungerand designed for the reception and retention of a spring 35, arranged tosupport and operate a presser-plate 36, normally disposed in a hori-.

zontal plane below the knife-edge of the cutter 32, but capable of beingpressed to a plane above the knife-edge when the cutter is presented tothe material placed upon the dieblock.

It is contemplated to provide for embossing in colors when desired, andit is therefore necessary to provide the machine with an inking devicefor applying ink to the embossing-die before each presentation of thelatter to the mount to be embossed. I have therefore devised a simpleform of inking mechanism comprehending an oscillatory inker, composed ofa pair of roller-carrying arms 37, pivotally mounted adjacent to theirupper ends upon studs 33, projecting from the op posite sides of theplunger-socket and having coincident slots 39 adjacent to their lowerfree ends for the reception of the trunnions 4.0.01 an inking-roller 41,yieldinglysustained by roller-sustaining springs 42, connected at theirlower ends to the trunnions 1O and at their upper ends to studsextending from the arms 37 above the slots. The roller etl is designedto be presented, through the oscillation of the arms 37, to an inkingtable or platen 4-3, having a curvature concentric with the axis ofmovement of the arms and extending forwardly from the front of theframe-standard 4. This inking table or plat-en may be formed in anysuitable manner; but a simple embodiment of this feature comprehends ametal plate recurved, as shown in Figs. 1 and 3 of the drawings, andhaving its ends screwed or bolted to the frame.

The upper end of each roller-carrying arm 37 is enlarged and is providedwith a transverse keeper 4.4, designed to receive and guide thetrip-bars 45, designed to reciprocate with the plunger and to haveoscillatory movement for the purpose of presenting the beaks 46 of saidbars into or out of a path of movement obstructed by shoulders 47,formed upon the enlarged end of each arm 37 to one side of the axes ofsaid arms. The shoulders 47 may be formed in any suitable manner so longas they serve to effect an operative engagement between the trip-bars 45and the roller-carrying arms 37 to swing the latter through thereciprocation of the plunger for the purpose of presenting the roller 41to the face of the embossing-d ie. The mounting of the trip-bars iseffected by passing a short shaft 48 through the apertured head 10 ofthe plunger, upon the ends of which shaft the trip-bars 45 are mountedto compel their longitudinal movement with the plunger, but permittingthem to have lateral or oscillatory movement independent thereof. Thesebars are normally held in position to engage the shoulders 47 by springs49, which maybe of any form and mounted in any desired position; but Iprefer to employ leaf-springs, asshown, depending below the keepers 44and bearing against the front edges of the bars. Under the impulse ofthe springs 49 the tripping-bars will be yieldingly urged to present thebeaks 46 under the shoulders 47 to cause the engagement of theseelements when the plunger is elevated for the purpose of swinging theinking-roller into contact with the embossing-die, as shown in fulllines in Fig. 1 of the drawings. It is evident, however, that means mustbe provided for throwing the inking mechanism out of operation when itis desired to emboss without printing or to em ploy the cutter. I havetherefore devised means for retaining the trip-bars in positions out ofoperative relation with the roller-carrying arms when the machineisdesigned to be used for the purposes stated. A simple embodiment of thismechanism is comprehended by a pair of retaining-pins 50, designed to beremovably inserted into openings in the enlarged ends of the arms 37 andin sliding contact with'the rear edges of the trip-bars 45 to retainsaid bars in forwardlydeflected positions, as indicated in Fig. 3 of thedrawings, and with the beaks 46 located beyond the vertical plane of theshoulders 47, so that the beaks will not engage the shoulders during theoperation of the plunger.

For the purpose of retaining the paper or card mounts in proper positionupon the block I provide an adjustable gage or guide 51, of angularform, and adjustably retained upon the upper face of the block 3 bymeans of a slotted guide-adjusting arm 52, through whose slot is passeda set-screw 53, retained within a threaded socket at a convenient pointin the die-block or in the base of the machine.

Assuming the device to be organized as illustrated in Fig. 1, theoperation is as follows: The card-mount is placed upon the die-block 3in a position determined by the gage or guide 51, and theoperating-lever is depressed to rock the plunger-lever 13 and to causethe reciprocation of the plunger for the purpose of presenting theembossing-die 27 to the mount, as indicated in dotted lines in Fig. 1.As the plunger begins its downward movement the trip-bars will releasethe arms 37 and permit them to swing back under the impulse of thespring to the position shown in dotted lines in Fig. 1 to present theinking-roller 41 to the inking platen or table 43. The release of theoperatinghandle 15 will now cause the retracting'spring 22 to draw theknuckle 17 of the toggle to the left, depressing the rear end of thelever '13 and causing the plunger to be raisedto its normal position.the plunger the trip-bars will engage the inking device, causing theinking-roller to be again swung into contact with the face of theembossing-die. If now it is desired to emboss card-mounts withoutprinting in colors, the

trip-bars 45 are swung forward to the positions indicated in Fig. 3 andare retainedby the insertion of the pins in their openings to preventthe engagement of the bars with the inking device as the plunger isreciprocated. \Vhen necessity arises for the use of the oval cutter forthe purpose of cutting photographic ovals, the set-screw 25 is loosenedand the die-holder is removed from the plunger. The cutter-head 29 isthen' attached to the lower end of the plunger, and the latter isreciprocated in the manner stated to present the oval or other form ofcutter 32 to the paper laid upon the die-block, the detachment of thepaper from the cutter as the latteris raised away from the block beinginsured by the movement of the spring-pressed plate 36.

From the foregoing it will be seen that I have produced a simple,powerful, and efif'b cient cutting and embossing machine which may bequickly equipped for the simultaneous cutting of a large number of papersheets or for the embossing of cardmounts and the like, either with orwithout colors; but while the embodiment of my invention illustrated anddescribed appears at this time to be preferable I do not wish to limitmyself to the structural details defined, as, on the contrary, I reservethe right to effect such changes, modifications, and variations as maybe properly comprehended within the scope of the protection prayed.
